xilinx_vdma_...l_set_config(9)

💅 NAME

Okay bestie, gather round, because tonight's main character is xilinx_vdma_channel_set_config — straight out of the Kernel API Manual, no cap. This is the function that does the Configure VDMA channel Run-time configuration for Axi VDMA, and it supports:

• . halt the channel
• . configure interrupt coalescing and inter-packet delay threshold
• . start/stop parking
• . enable genlock

Like, that's the whole vibe check in one function. Obsessed. 🫶

✨ SYNOPSIS

int xilinx_vdma_channel_set_config (struct dma_chan *dchan , struct xilinx_vdma_config *cfg );

Yeah she returns an int, she takes two pointers, she's booked and busy. 💅

---

🎀 ARGUMENTS

• dchan — the DMA channel. This is your girl, the actual channel you're coming in to configure. ✨
• cfg — VDMA device configuration pointer. This is the lil bundle of settings you're handing over, iykyk. 🎁

---

💀 RETURN

Literally nothing here. The return section is empty, bestie. (crickets 🦗) The original page gives us no return-value info, so I'm not gonna invent any. Not today, not ever. 🙈

Mwah, that's the whole page! This lil masterpiece lives over in ./drivers/dma/xilinx, dated October 2026, and it goes by xilinx_vdma_...l_set_config(9) — yes the name is truncated in the middle, she's mysterious like that. 🎀✨ Byeee, go configure some channels, ily! 💖🦋
